- 2. Multiple ChoiceWhich of the following is an example of internal regulation during the cell cycle?A gap outside of the cell (caused by a skateboarding accident) triggers cell division.A cell receives a signal from the cell’s own nucleus to divide.Tumor cells continue to divide without receiving a signal.Hormones in the blood cause cell growth in a growing teenager.
- 3. Multiple ChoiceOrganize the parts of this body system in the CORRECT order (starting with the organism level) according to the levels of organization in a multi-cellular organism.human being → central nervous system → brain → nerve tissue → neurons (brain cell)human being → neurons (brain cell) → brain → central nervous system → nerve tissuehuman being → central nervous system → neurons (brain cell) → nerve tissue → brainhuman being → brain → central nervous system → nerve tissue → neurons (brain cell)
- 4. Multiple ChoiceWhich of the following is true of malignant tumors?They do not require treatment.They are easily removed through surgery.They can cause tumors in other parts of the body.They contain cells that stay clustered together.
- 5. Multiple ChoiceIf a cell has 8 chromosomes, how many chromosomes will each of its daughter cells have after mitosis?46816
- 6. Multiple ChoiceDuring interphase, a cell grows, duplicates organelles, andDivides the nucleusCopies DNADivides the cytoplasmProduces a new cell
- 7. Multiple ChoiceWhich organelle is critical for cell division?Centrioles/CentrosomesCiliaVacuolesVesicles
- 8. Multiple ChoiceWhy is it important for cells of multicellular organisms to undergo mitosis?Mitosis allows for reproduction with male and female gametes.Mitosis increases variation within an organism.Mitosis produces cells that are different from the original dividing cell.Mitosis produces cells that are identical to the original dividing cell.
- 9. Multiple ChoiceSubstances known to produce or promote cancer are calledKinasesCarcinogensCyclinsMalignancies
- 10. Multiple ChoiceWhat makes stem cells different from other cells in the body?They are larger than other cells, and can absorb broken cells to repair them.They repair cells by breaking open and making their cell parts available for absorption into other cells.They are undifferentiated cells that can turn into a number of different kinds of cells as needed.They are cells that grow uncontrollably.
- 11. Multiple ChoiceOne difference between a cancer cell and a normal cell is thatCancer cells divide uncontrollablyNormal cells divide uncontrollablyCancer cells cannot make copies of DNANormal cells cannot make copies of DNA
